To the hottie with the shower massager addiction :

While in bed with your H as he snores, try stroking the "bull's horn". If it wakes him up, pull your hand away and act like you are asleep. (He might think his own hard-on woke him up.) He'll be faced with the choice of doing something about it or going back to sleep. If it's the first, you win! If he goes back to sleep, do the same thing when he begins snoring again. Eventually, he'll have to face up to his "stimulation".

(The other option I just considered is that he'll get an erection without waking up. If so, insert Tab A into Slot B and see how far you can get before he wakes up. )
